$DDT$

Vedclass · Answer

(D) The decline in the population of birds and reptiles is primarily caused by the accumulation of $DDT$ (Dichlorodiphenyltrichloroethane) in the environment. $DDT$ is a persistent organic pollutant that undergoes biomagnification,meaning its concentration increases as it moves up the food chain. High levels of $DDT$ in birds interfere with calcium metabolism,leading to the thinning of eggshells,which causes them to break prematurely during incubation,resulting in a decline in their population.
